Today when I went into our Admin Dashboard we had the notification: Your Discourse installation is out of date. Click here to update. I first clicked the button to Update Docker. When the completed, from the Admin Dashboard, I again visited admin/update again, only to find that screen was blank within the “Admin/Update” frame. Screenshot [Snapshot 2025-01-15 at 12.44.35@2x] I tried clearing browser cache/cookies and also disabling some theme components, etc. I logged in via root to my server console and tried to run ./launcher rebuild app and got this error: :warning: “ERROR: Docker version 18.09.6 not supported, please upgrade to at least 20.10.0, or recommended 24.0.7” Our site is still working just fine… but I can’t upgrade Docker via the UI. Is there a way to safely upgrade docker via SSH Console, and try to rebuild the app after that? Some other points to consider: We are currently on Docker version 18.09.6, build 481bc77 While Docker was updating via the Admin interface, I was logged into my console and attempting to add a plugin via nano containers/app.yml so maybe that caused some kind of conflict?? I have since deleted the two apps that I was attempting to add: - https://github.com/discourse/discourse-akismet.git and https://github.com/discourse/discourse-ai.git

Does cat /etc/issue suggest that you have 18.04? You can try apt update;apt install docker-ce Another way, that prints a scary message, but is probably safe if you installed docker with apt wget -qO- https://get.docker.com/ | sh

After that, I tried to update Discourse via the terminal (I use DigitalOcean’s Droplet Console). However, when running the command ./launcher rebuild app, I get this error: ERROR: Docker version 19.03.13 not supported, please upgrade to at least 20.10.0, or recommended 24.0.7. But I had already done the update through the “Upgrade” admin interface on the website. Now nothing is working anymore. What could have gone wrong?

Move a Discourse site to another VPS with rsync

You were right. Getting a new Ubuntu OS was probably the best way to go. I just went through the process of creating another install on a Digital Ocean droplet. then updated my DNS records and uploaded a backup from our old community. Everything is working great now! Thanks!
